I ROLLER SKATE AND WHEEL THEREFOR.

Application filed May 25,

To all whom it may concern: Be it known that O'r'ro W. BOCHE, a citizenof the United States, and resident of Bridgeport, in the county ofFairfield and State of Connecticut, has invented certain new and usefulImprovements in Roller Skates and Wheels Therefor, of which thefollowing is a specification. I

This invention relates to roller skatesand to wheels therefor. I

An object of the invention is to produce an improved roller skate ofsimple, practical and durable construction and of llght weight, and toprovide therein novel means for mounting the skate wheels, sald novelmeans consisting of certain of the elements of both said skateandwheels. A further object is to provide a novel and improved skatewheel that can be ec0nom-' ically manufactured and will be reliable andeflicient in use.

With the above, as well as .other, objects in view, the construction,arrangement and combination of parts constituting the. invention willnow be fully described, reference being had to the accompanying drawingforming a part of this specification and wherein like reference numeralsdesignate corresponding parts throughout the several figures, and willbe hereinafter specifically claimed, it being understood that suchchanges in details ofconstruction and arrangement of parts maybe made asfall within the spirit of the invention and within the scope of theclaims.-

In said drawings,

Fig. 1 is a side elevational viewon a reduced scale of a skate embodyingthe. fea- Y angular positions with respect to the foot tures of theinvention. Fig. 2 is a sectional view on line 2'2 1n Fi 1' Fig. 3 is asectional view Fig. 1;

on line 3-3 in Fig. 4 is a detail perspective View of portions of thefoot plate-and one of the side plates, illustrating the connectionbetweeh said plates; and

Fig. 5 is a, sectional view, corresponding 1 with the showing of Fig. 3,disclosin a modified form of axle, that may be utilized for. mountingthe skate wheels. 7

Of the novel skate, 10 denotes a metal foot plate and 11 and 12 denote,respectively,

to rest 1 1921. Serial No. 472,430.

clamp members of ordinary or preferred constructlon and for an obviouspurpose.

13 and 14 denote, respectively, spaced" apart, parallel metal sideplates arranged longitudinally of the foot plate adjacent the oppositeside edges thereof and extending downwardly at right-angles therefrom toprovlde supportin means for the solid axles,

denoted by 15, of t e skate wheels. ,The side plates are cut away at'theseveral locations indicated 16 for the sakeof li htness, thus providingattaching portions 1 positioned directly above the axles', whereby theside foot plate, the detachable connection being preferably made in themanner best shown the slot 19, as will be understood. I

The axles 15 are provided at their 0p'po-- site ends with reducedportions 23, and the side plates'are provided with openings tov snuglyreceive said reduced portions. The axles are fixed against rotation inthe side plates, so that while one of the reduced portions 23 may becylindrical, the otherone is platescan be detachably connected with the.

flat 'on one side, as best shown at 24in Fig.

L See also the hole25 in that portion of the side plate '13 shown inFig. 4.. The side plates'may be held in their rightplate and against theends of the larger portions of the axles 15 by means 'of screw boltsplates and each provided with a head 27 anda nut 28 bearingagainst theouter faces, respectively, of'the si e plates. .29 represents bushingslocated upon thecscrew bolts and arranged between the side plates, saidbush ingsjbeing of the same length asare the larger portions of theaxles, .foran apparent reason. v

In Fig. '1 of the drawing I have shown' a skate equipped with fouraxles, with an equal number-of attaching portions 17, and

7 the running surfaces of the two intermediate skate Wheels will be atslightly lower elevation than are @the running surfaces of the front andrear wheels.

It will be evident that the side plates cannot be disconnected from thefoot. plate so K long as said side plates bear their ri htlllii angularrelation to the foot plate. W en, however, the screw bolts 26 areremoved from the side plates, saidlast mentioned" plates can be readilyswung outwardly to remove the tongues 17 from the slots 19.

The skate wheels are all du licates of each other. Of each of said whees, 30 denotes a pair of disks detachably secured together as by means ofsmall screw bolts 31.-

Each of said disks is provided with a central opening 32 to freelyreceive the solid axle 15, and adjacent said opening the disks areflared outwardly, as denoted at 33, to receive metal balls, denoted by34, adapted to rest within a circumferential groove 35 in the peripheryof the axle 15 and arranged midway between the ends of the largerportion of said axle. Said disks are also flared outwardly adjacenttheir circumferential margins, as denoted at 36, to provide a bearingrim for the snug reception of the tire 37 composed of hard rubber orother suitable material. I I

It has already been remarked that the solid axles 15 are fixed in theside plates. It is to be now remarked that the outwardly flared portions33 of the disks comprise the hubs of the skate wheels, said hubs ridingover the metal balls 34 andsaid balls ridin over the groove 35 of theaxle.

In Fig. 5 I have disclosed a modified form a of solid axle which may beemployed in connection with the features of the present invention andwhich has been designed for use in the instance of double wheel skates.The foot plate, side plates and wheels in the present embodiment may beof the approximate construction of those already do- I scribed.

The axles 15, extending throu h the side plates and projecting some litte distance beyond each side plate, as denoted at38, are

provided with a collar 39 en aging the side plate 14. and with a threadeportion 40 to receive a nut 41 engaging the side plate '13. Bushings 42,one for each axle 15 and between the side -plates, serve the purpose,already described, served by bushings 29. Obviously, a single wheelskate axle 15- can be rovided with a bushing similar to the bus ing 42to serve the same purpose, and

when such an arrangement is employed, the

- screw bolts 26 may be dispensed with if this is found desirable.against rotation tion 24'.

The grooves 35, 35 in the projecting portions 38 of the axle 15 servethe same purpose as do the grooves 35 in the axles 15.

Having thus fully described the invention, what I claim and desire tosecure by Letters Patent is:

1. A. roller skate comprising a foot plate, a pair or parallel,disconnected and spaced apart side plates extending downwardly at Theaxle 15' is fixed by means of the fiat poriright-angles from adjacentthe opposite edges of the foot plate for a proximately the length ofsaid skate, space a art means on each side plate detachably anseparately connecting the, same to said foot plate, said means in theinstance of each side plate being arranged along, the greater part ofthe length of said skate, means forinsuring the positions of the sideplates, axles fixed in and extending between said plates, and wheels onsaid axles...

2. A roller skate comprising afoot plate,

a pair of parallel, disconnected side plates extending downwardly atright-angles from adjacent the opposite edges thereof for apthrough a,slot adjacent the sideedge of saidfoot plate. I,

'3. A roller skate comprising a foot plate, a pair of parallel sideplates-extending downwardly at'right-angles from adjacent theoppositeedges thereof, means for detachably connecting said side platesto said foot plate,-axles fixed in and extending between said sideplates, means for insuring the positions of the side plates, and wheelson said axles, said connecting m'eans in the instance of each side plateincluding a tongue extending atright-an les from the flat upper edge ofsaid side p ateand passing through a slot adjacent the side edge of saidfoot late, the body of said tongue resting in a epression in said footplate.v

4. A roller skate comprising a foot-plate,

a pair of parallel side plates extending downwardly at right-anglesfrom. adjacent the opposite edgesthereofimeans for detachably connectingsaid side plates to said foot said side plates, means for insuring thepositionsof the side plates, and wheels on said axles, said connectingmeans in the instance of each side plate including a; tongue ex- "plate,axles fixed in and extending between tending at right-angles from theflat upper edge of said side plate and passing through a slot adjacentthe side edge of said foot plate, the body of said tongue resting in adepression in said foot plate, and the rightangular bend in said tonguelocated in the plane of said foot plate and contiguous with the Wall ofsaid slot farthest 'from said depression.
